Charlie did not meet his goal because he used more than 50 gallons per day.

Step-by-step explanation:

Let,

x be the number of gallons used by charlie.

Charlie's goal;

x<50

Gallons used in 30 days = 1524 gallons

Gallons used in 1 day = \frac{Total\ gallons}{No.\ of\ days}

Gallons used in 1 day = \frac{1524}{30} = 50.8

Therefore,

Charlie used 50.8 gallons of water per day.

Charlie did not meet his goal because he used more than 50 gallons per day.

A data set whose original x values ranged from 120 through 351 was used to generate a regression equation of ŷ=0.06x + 14.2. Use
lawyer [7]

Answer:

35.32

Step-by-step explanation:

The regression equation usually demonstrated as

y=a+bx.

In the above equation y is the dependent variable, x is the independent variable, a is the intercept of regression line and b is the slope of regression line.

The given regression equation is

y^=0.06x+14.2

The predicted value of y can be computed by simply putting the value of x in above equation.

So,

y^=0.06(352)+14.2

y^=21.12+14.2

y^=35.32

Thus, the predicted value of y for x=352 is 35.32.

One of two complementary angles measures 30 degrees more than three times the other. Find each angle.
Leviafan [203]

The two complementary angles are:

95° and 15°

Step-by-step explanation:

Let x be one angle

then the other angle will be 90-x

As the sum of complementary angles is 90

So,

then according to statement

x = 3(90-x)+30\\x = 270-3x +30\\x = 300-3x\\x+3x = 300\\4x = 300\\x = \frac{300}[4}\\x = 75\\and\\90 -x = 90 - 75 = 15

The two complementary angles are:

95° and 15°

Can u plz help me i don't get it
marishachu [46]

Answer:

w=9x+4


Step-by-step explanation:

2(3x-3+w)=12x+2

6x-6+2w=12x+2

subtract 6x for both sides

-6+2w=18x+2

add 6 for both sides

2w=18x+8

Divide by 2 to find w

w=9x+4
